Discussion | Subspecies 4 (4 in the flora). References to Gentianopsis detonsa in the Rocky Mountains from Montana south to New Mexico have been based on circumscriptions of the species that included G. thermalis. Specimens formerly so identified from Illinois, Indiana, and Ontario south of the James Bay region are G. virgata subsp. virgata. Those from Minnesota are G. virgata subsp. macounii.
